Overview of the structure of the coal slagging property tester The instrument mainly consists of the main engine, the flue gas chamber, the air chamber, the gasification sleeve, the pipeline system, the flow meter, the air control valve, etc. The machine body is welded with cold-rolled steel plate, which mainly plays the role of the combined machine parts. The flue gas chamber and the air chamber are convenient for observing the functions of air flow, air pressure, gas gathering, etc. The gasification sleeve is the material combustion chamber. The pipeline system plays the direction of the flow gas; the rotor flowmeter is a special accessory for observing the gas pressure value; the needle gas control valve is used to control the air flow and pressure
